SMARTER Example to test demo without the need to have physical cameras or microphones
Using this workload will allow pulseaudio to pickup a fake microphone device which is playing the audio output of demo.mp4
A pulseaudio client can access the audio generated by setting the env PULSE_SOURCE=alsa_input.platform-snd_aloop.0.analog-stereo
To enable the use of this workload you must load the following two modules on your host:
sudo modprobe snd-aloop
sudo modprobe v4l2loopback card_label="My Fake Webcam" exclusive_caps=1
